装置。[Claims for Utility Model Registration] 1. A telescopic fluid pressure cylinder consisting of a plurality of cylinder members is installed inside a supporting outer cylinder formed by interconnecting a plurality of cylindrical members in a telescopic manner,
In a telescopic cylinder device arranged opposite to and interlocking with the support outer cylinder, the cylinder member with the smallest diameter in the fluid pressure cylinder is integrated with the cylindrical member with the largest diameter in the support outer cylinder. and the cylinder member with the largest diameter is slidably supported with respect to the cylindrical member with the smallest diameter,
A telescopic cylinder device characterized in that when the cylinder device is extended, the cylinder member with the largest diameter protrudes from the tip of the cylindrical member with the smallest diameter. 2. When the cylinder device is at its maximum extension, the sliding support member provided at the base end of the first stage (next to the maximum diameter) cylinder member in the telescopic fluid pressure cylinder becomes the cylindrical member with the smallest diameter in the supporting outer cylinder. The telescope type according to claim 1, characterized in that the telescope type is configured to protrude inward of the cylinder member having the maximum diameter beyond the position of the sliding support member provided at the tip end of the telescope type. cylinder device. 3. A sealing member between the cylinder member with the maximum diameter and the first stage cylinder member is provided on the inner peripheral surface side of the cylinder member with the maximum diameter, and the seal member in the final stage (minimum diameter)
A telescope type according to claim 1 of the utility model registration claim, characterized in that a sealing member between the cylinder member and the cylinder member immediately before the cylinder member is provided on the outer peripheral surface side of the cylinder member in the final stage. cylinder device.
